I am in a rather unique situation. I've inherited a zpool composed of two vdevs. One vdev was roughly 9TB on one RAID 5 array, and the other vdev is roughly 2TB on a different RAID 5 array. The 9TB array crashed and was sent to a data recovery firm, and they've given me a dd image. I've also taken a dd image of the other side.
-rw-r--r-- 1 root wheel 9.2T Aug 18 07:53 deep_Lun0.dd -rw-r--r-- 1 root wheel 2.1T Aug 23 15:55 deep_san01_lun.dd zpool import identifies that both files are members of the pool, but there are 'insufficient replicas' and it can not import. zpool import -d . -F pool: deep id: 8026270260630449340 state: UNAVAIL status: The pool was last accessed by another system. action: The pool cannot be imported due to damaged devices or data. see: http://www.sun.com/msg/ZFS-8000-EY config: deep UNAVAIL insufficient replicas /jbod1-diskbackup/restore/deep_san01_lun.dd UNAVAIL cannot open /jbod1-diskbackup/restore/deep_Lun0.dd UNAVAIL cannot open Using zdb, I can see both images have 4 labels. What are my options in terms of attempting a recovery? I had hoped that ZFS could import the pool even if the vdevs are now files instead of devices, but unfortunately it was not so easy. zdb -l deep_Lun0.dd --------------------------------------------
